Description

Technical Field

[0001] This invention relates to the field of polishing technology, specifically to a polishing and grinding device for use before powder coating. Background Technology

[0002] In the powder coating process, polishing is a crucial preliminary step, directly affecting the adhesion, smoothness, and aesthetics of the powder coating. High-quality polishing removes surface imperfections, oxide layers, and roughness, creating an ideal base for powder coating. Polishing equipment treats the workpiece surface through mechanical force, friction, or chemical action. Common mechanical polishing methods, such as using abrasive belts, grinding wheels, and polishing wheels, utilize equipment to drive these tools at high speeds, bringing them into close contact with the workpiece surface. Friction removes surface bumps and imperfections, reducing surface roughness. Chemical polishing, on the other hand, relies on specific chemical solutions to react with the workpiece surface, dissolving microscopic high points and achieving a smooth and glossy surface.

[0003] Existing polishing and grinding equipment has certain defects in material fixation, resulting in insufficient fixation of materials with slight differences in size or shape, which can easily lead to displacement and sparks during the grinding process. These issues have not been taken seriously and can easily cause safety hazards. Therefore, a new design has been developed to address these problems. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a polishing and grinding equipment for powder coating processing, comprising a composite mechanism, a processing mechanism fixedly connected to the outer side of the composite mechanism, and a motor fixedly connected to the bottom of the composite mechanism;

[0005] The composite mechanism includes a composite platform. A steering mechanism is fixedly connected to the center of the top of the composite platform. The steering mechanism is rotated by a motor, thereby rotating the material. A clamping mechanism is fixedly connected to the top of the steering mechanism to hold the material securely, maintaining its stability and preventing it from affecting the grinding effect during subsequent operations. A buffer mechanism is fixedly connected to the center of the top of the clamping mechanism. Cylindrical materials are placed on top of the buffer mechanism to reduce the impact of material placement, decrease wear between components and materials, reduce vibration amplitude on the equipment, and improve stability during material placement. The center of the bottom of the composite platform is fixedly connected to the outside of the motor. Frictional adaptation between the rotating material and the processing mechanism achieves [the desired effect]. The motor's output end is fixedly connected to the bottom of the steering mechanism for grinding and polishing materials. A first electric push rod is fixedly connected to the top edge of the composite platform. During the grinding process, a lot of sparks and debris are generated. The first electric push rod controls the annular plate to rise outside the annular base plate, thereby shielding the area during operation, limiting sparks, reducing safety hazards, and preventing fires. An annular plate is fixedly connected to one side of the top of the first electric push rod. A folding layer is fixedly connected to the middle of the outer side of the annular plate. The folding layer in the middle section of the annular plate increases the lifting and shielding coverage area, making it easy to adjust according to the length of the material and improving the applicability of the equipment. An annular base plate is slidably connected to the bottom of the annular plate, and the bottom of the annular base plate is fixedly connected to the top of the composite platform.

[0006] Preferably, the steering mechanism includes a steering housing, an annular rail rotatably connected to the inner side of the steering housing, a driven block fixedly connected to the inner side of the annular rail, the driven block rotating within the steering housing via the annular rail to maintain normal operation, a driving block meshing with the inner side of the driven block, a connecting shaft fixedly connected to the inner side of the driving block, the bottom of the connecting shaft fixedly connected to the output end of a motor, the motor controlling the rotation of the connecting shaft, the driving block meshing with the inner side of the driven block during rotation to maintain stability during rotation, a steering top plate fixedly connected to the top of the connecting shaft, the rotation of the connecting shaft driving the rotation of the steering top plate, the steering top plate driving the clamping mechanism to rotate, thereby causing the material to rotate and rub against the processing mechanism to achieve polishing and grinding of the material, the top of the steering top plate being fixedly connected to the bottom of the clamping mechanism.

[0007] Preferably, the clamping mechanism includes a clamping base with a square groove on its top. A sliding block is slidably connected to the inner side of the square groove. The sliding block moves towards the center of the clamping base from the inner side of the square groove, thereby clamping and fixing the material to maintain stability in subsequent operations. A clamping mechanism is inserted into the inner side of the sliding block to facilitate disassembly, replacement, and subsequent maintenance. The clamping mechanism can adjust the adhesion to the material to further improve the clamping effect and prevent the material from derailing.

[0008] Preferably, the clamping mechanism includes a clamping housing, with a cylindrical groove formed on one side of the outer surface of the clamping housing. A first spring is fixedly connected to the inner side of the cylindrical groove, and a sliding rod is fixedly connected to the outer side of the first spring. When clamping material, the reaction force generated by the material compresses the first spring, thereby facilitating expansion and contraction to fit the material shape. Then, the reaction force of the first spring supports the sliding rod, thereby increasing the clamping effect on the material and providing a certain anti-slip effect, thus improving the clamping function.

[0009] Preferably, a connecting block is threadedly connected to the side of the sliding rod away from the first spring, and a silicone block is fixedly connected to the side of the connecting block away from the sliding rod. The silicone block is made of silicone material to increase the wear resistance of the component, reduce wear during clamping, extend the service life of the component, and provide a certain cushioning effect and protection for the component. The outer side of the silicone block is provided with a curved groove to enhance flexibility and cushioning performance, improve breathability and heat dissipation, and increase friction and anti-slip effect.

[0010] Preferably, the buffer mechanism includes a buffer frame, the outer side of which is fixedly connected to the inner side of the circular groove of the clamping base. A connecting rod is slidably connected to the top of the buffer frame, and a receiving plate is fixedly connected to the top of the connecting rod. A silicone pad is fixedly connected to the top of the receiving plate. When material is placed on the top of the silicone pad, the silicone pad provides an anti-slip effect and increases wear resistance, reducing equipment wear and extending the service life of the components. It also increases the anti-slip effect of the material and improves the stability of the placed material. A second spring is sleeved on the outer side of the connecting rod near the receiving plate. The impact generated by the placed material compresses the connecting rod, causing the second spring to contract, thereby achieving a shock absorption and buffering effect, reducing the amplitude of the material and avoiding affecting the stability of the equipment.

[0011] Preferably, a receiving bracket is slidably connected to the outer side of the connecting rod, and the top of the receiving bracket is fixedly connected to the bottom of the buffer frame. A third spring is sleeved on the outer side of the connecting rod near the receiving bracket. When the material is removed, the second spring rebounds, which can easily cause the component to vibrate, and excessive rebound can easily damage the component. Therefore, when the second spring rebounds, the tension of the connecting rod compresses the third spring, which provides shock absorption and buffering, thereby slowing down the rebound of the component, improving the stability of the component, and providing a certain degree of protection for the component.

[0012] Preferably, the processing mechanism includes a processing base, one side of which is fixedly connected to the outer side of the composite platform. A second electric push rod is fixedly connected to the top of the processing base, which raises and lowers to control the height of the component, facilitating adjustment according to the material's grinding surface. A telescopic bracket is fixedly connected to one side of the top of the second electric push rod, allowing the friction mechanism to fit against the material surface, thus facilitating the application of materials of different sizes and avoiding affecting the grinding effect. A third electric push rod is fixedly connected to the top of the telescopic bracket on the side away from the second electric push rod, controlling the raising and lowering of the receiving column to improve the component's flexibility and increase the control details. Then, by rotating the material and rubbing it against the friction mechanism, the polishing effect is achieved. A receiving column is rotatably connected to the outer side of the third electric push rod, and a friction mechanism is fixedly connected to the outer side of the receiving column.

[0013] Preferably, the friction mechanism includes a receiving block, one side of which is fixedly connected to the outer side of a receiving column. A fourth spring is provided on the inner side of the receiving block, and a cylindrical block is fixedly connected to the outer side of the fourth spring. When in contact with the surface of the rotating material, the cylindrical block slides inward to the receiving block according to the external pressure, thereby facilitating the deformation of the component through contraction and thus conforming to the material surface, improving the grinding effect, reducing grinding dead angles, and expanding the applicability of the equipment. An annular flexible plate is fixedly connected to the outer side of the cylindrical block away from the fourth spring. A friction belt is sleeved in the groove on the outer side of the annular flexible plate away from the cylindrical block. The friction belt rubs against the material surface to achieve the grinding effect. A square cut is provided on the outer side of the friction belt. By opening the square cut and slotting, the chip removal effect is enhanced, thereby reducing impurity adsorption. Secondly, the slotting enhances the heat dissipation effect, effectively reducing the heat generated by friction and preventing the material from overheating and deforming.

[0014] This invention provides a polishing and grinding device for use before powder coating. It has the following beneficial effects:

[0015] I. This polishing and grinding equipment for pre-powder coating uses a composite mechanism design. Cylindrical materials are placed on top of a buffer mechanism to mitigate impact, reduce wear between components and materials, lower vibration levels, and improve stability during material placement. A clamping mechanism holds the material securely, maintaining its stability and preventing it from affecting the polishing effect during subsequent operations. A motor-controlled steering mechanism rotates the material, allowing it to rotate and rub against the processing mechanism, thus polishing the material. During polishing, numerous sparks and debris are generated. A first electric push rod controls the annular plate to rise outside the annular base plate, acting as a shield to limit sparks, reduce safety hazards, and prevent fires. Furthermore, a folding layer in the middle of the annular plate increases the lifting and shielding coverage area, allowing for adjustments based on material length and expanding the equipment's applicability.

[0016] II. This polishing and grinding equipment for powder coating processes features a clamping mechanism designed with the clamping mechanism inserted inside the sliding block. This facilitates disassembly, replacement, and subsequent maintenance. The sliding block moves from the inside of the square groove towards the center of the clamping base, thereby clamping and fixing the material. This ensures stability for subsequent operations. Furthermore, the clamping mechanism allows for adjustment of the material's adhesion, further enhancing the clamping effect and preventing material derailment.

[0017] III. This polishing and grinding equipment used before powder coating processes, through the design of the clamping mechanism, compresses the first spring when the material is clamped, thus facilitating the expansion and contraction to fit the shape of the material. Then, the reaction of the first spring supports the sliding rod, thereby increasing the clamping effect on the material and providing a certain anti-slip effect, thereby improving the clamping performance. The silicone block is made of silicone material, thereby increasing the wear resistance of the components, reducing wear during clamping, and extending the service life of the components. It also provides a certain cushioning effect and protects the components. Furthermore, by opening curved grooves, the flexibility and cushioning performance are enhanced, the breathability and heat dissipation performance are improved, and the friction and anti-slip effect are increased.

[0018] IV. This polishing and grinding equipment used before powder coating processes features a buffer mechanism design. When materials are placed on top of a silicone pad, the silicone pad provides an anti-slip effect and increases wear resistance, reducing equipment wear and extending the service life of components. Secondly, it enhances the anti-slip effect of materials, improving the stability of material placement. The impact generated by placing materials compresses the connecting rod, causing the second spring to contract, thus achieving a shock-absorbing and buffering effect, reducing the amplitude of material vibration and preventing it from affecting the stability of the equipment. When the material is removed, the second spring rebounds, which can easily cause component vibration, and excessively rapid rebound can damage components. Therefore, when the second spring rebounds, the tension of the connecting rod compresses the third spring, which provides shock absorption and buffering, thus slowing down the rebound of components, improving component stability, and providing a certain degree of protection for the components.

[0019] V. This polishing and grinding equipment for pre-powder coating processes utilizes a friction mechanism design. A friction belt rubs against the material surface to achieve the grinding effect. Square cuts and grooves enhance chip removal and reduce impurity adsorption. Furthermore, the grooves enhance heat dissipation, effectively reducing heat generated by friction and preventing material overheating and deformation. When in contact with the rotating material surface, external pressure causes the cylindrical block to slide inwards towards the receiving block, facilitating deformation through contraction and conforming to the material surface. This improves the grinding effect, reduces grinding dead angles, and expands the equipment's applicability. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] First embodiment, such as Figures 1 to 4 As shown, the present invention provides a technical solution: a polishing and grinding device for powder coating, including a composite mechanism 1, a processing mechanism 2 fixedly connected to the outside of the composite mechanism 1, and a motor 3 fixedly connected to the bottom of the composite mechanism 1;

[0033] The composite mechanism 1 includes a composite platform 11. A steering mechanism 16 is fixedly connected to the middle of the top of the composite platform 11. A clamping mechanism 17 is fixedly connected to the top of the steering mechanism 16. A buffer mechanism 18 is fixedly connected to the middle of the top of the clamping mechanism 17. The middle of the bottom of the composite platform 11 is fixedly connected to the outside of the motor 3. The output end of the motor 3 is fixedly connected to the bottom of the steering mechanism 16. A first electric push rod 12 is fixedly connected to the edge of the top of the composite platform 11. An annular plate 13 is fixedly connected to one side of the top of the first electric push rod 12. A folding layer 14 is fixedly connected to the middle of the outside of the annular plate 13. An annular bottom plate 15 is slidably connected to the bottom of the annular plate 13. The bottom of the annular bottom plate 15 is fixedly connected to the top of the composite platform 11. The cylindrical material is placed on top of the buffer mechanism 18 to reduce the impact of material placement, reduce wear between parts and materials, reduce the amplitude of vibration on the equipment, and improve the stability of the material during placement. The clamping mechanism 17 fixes and holds the material to maintain its stability and prevent it from affecting the stability of the material during subsequent operations, thus preventing the grinding effect from being affected. The steering mechanism 16 is rotated by the motor 3 to rotate the material. The material rotates and rubs against the processing mechanism 2 to achieve the grinding and polishing effect. During the grinding process, a lot of sparks and debris are generated. The first electric push rod 12 controls the ring plate 13 to rise outside the ring base plate 15 to shield the sparks during operation, reduce safety hazards, and prevent fires. Secondly, a folding layer 14 is set in the middle section of the ring plate 13 to increase the lifting and shielding coverage area, which is easy to adjust with the length of the material and improves the applicability of the equipment.

[0034] The steering mechanism 16 includes a steering housing 161, an annular rail 163 is rotatably connected to the inner side of the steering housing 161, a driven block 162 is fixedly connected to the inner side of the annular rail 163, a driving block 164 is meshed with the inner side of the driven block 162, a connecting shaft 165 is fixedly connected to the inner side of the driving block 164, the bottom of the connecting shaft 165 is fixedly connected to the output end of the motor 3, a steering top plate 166 is fixedly connected to the top of the connecting shaft 165, and the top of the steering top plate 166 is fixedly connected to the bottom of the clamping mechanism 17. The connecting shaft 165 is rotated by the motor 3. When the connecting shaft 165 rotates, the driving block 164 engages with the driven block 162 inside to maintain stability during rotation. The driven block 162 rotates inside the steering housing 161 via the annular rail 163 to maintain normal operation. During the rotation of the connecting shaft 165, the steering top plate 166 is driven to rotate, and the steering top plate 166 drives the clamping mechanism 17 to rotate, thereby causing the material to rotate and rub against the processing mechanism 2, thus achieving polishing and grinding of the material.

[0035] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 5 to 8 As shown, the clamping mechanism 17 includes a clamping base 171. A square groove 172 is provided on the top of the clamping base 171. A sliding block 173 is slidably connected to the inner side of the square groove 172. A clamping mechanism 174 is inserted into the inner side of the sliding block 173. The clamping mechanism 174 is inserted into the inner side of the sliding block 173 to facilitate disassembly, replacement, and subsequent maintenance. By moving the sliding block 173 from the inner side of the square groove 172 toward the center of the clamping base 171, the material is clamped and fixed, thus maintaining the stability of subsequent operations. Furthermore, the clamping mechanism 174 can adjust the adhesion effect to the material, thereby further improving the fixing and clamping effect and preventing the material from derailing.

[0036] The clamping mechanism 174 includes a clamping housing 1741. A cylindrical groove 1742 is formed on one side of the outer side of the clamping housing 1741. A first spring 1743 is fixedly connected to the inner side of the cylindrical groove 1742, and a sliding rod 1744 is fixedly connected to the outer side of the first spring 1743. When clamping material, the reaction force generated by the material compresses the first spring 1743, thereby facilitating its expansion and contraction to fit the material shape. Then, the reaction force of the first spring 1743 supports the sliding rod 1744, thereby increasing the clamping effect on the material and providing a certain anti-slip effect, thus improving the clamping function.

[0037] A connecting block 1745 is threadedly connected to the side of the sliding rod 1744 furthest from the first spring 1743. A silicone block 1746 is fixedly connected to the side of the connecting block 1745 furthest from the sliding rod 1744. A curved groove 1747 is formed on the outer side of the silicone block 1746. The silicone block 1746 is made of silicone to increase the wear resistance of the component, reduce wear during clamping, and extend the service life of the component. It also provides a certain cushioning effect and protection for the component. Furthermore, the curved groove 1747 enhances flexibility and cushioning performance, improves breathability and heat dissipation, and increases friction and anti-slip effect.

[0038] The buffer mechanism 18 includes a buffer frame 181. The outer side of the buffer frame 181 is fixedly connected to the inner side of the circular groove of the clamping base 171. A connecting rod 184 is slidably connected to the top of the buffer frame 181. A receiving plate 182 is fixedly connected to the top of the connecting rod 184. A silicone pad 183 is fixedly connected to the top of the receiving plate 182. A second spring 185 is sleeved on the outer side of the connecting rod 184 near the receiving plate 182. When material is placed on top of the silicone pad 183, the silicone pad 183 provides an anti-slip effect and increases wear resistance, reducing equipment wear and extending the service life of components. It also increases the anti-slip effect of the material, improving the stability of the placed material. The impact generated by the placed material compresses the connecting rod 184, causing the second spring 185 to contract, thereby achieving a shock absorption and buffering effect, reducing the amplitude of the material vibration and preventing it from affecting the stability of the equipment.

[0039] A receiving bracket 186 is slidably connected to the outer side of the connecting rod 184. The top of the receiving bracket 186 is fixedly connected to the bottom of the buffer frame 181. A third spring 187 is sleeved on the outer side of the connecting rod 184 near the receiving bracket 186. When the material is removed, the second spring 185 rebounds, which can easily cause the component to vibrate. Excessive rebound can also damage the component. Therefore, when the second spring 185 rebounds, the tension of the connecting rod 184 compresses the third spring 187, which provides shock absorption and buffering, thereby slowing down the rebound of the component, improving its stability, and providing a certain degree of protection.

[0040] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 9 to 10 As shown, the processing mechanism 2 includes a processing base 21. One side of the processing base 21 is fixedly connected to the outer side of the composite platform 11. A second electric push rod 22 is fixedly connected to the top of the processing base 21. A telescopic bracket 23 is fixedly connected to one side of the top of the second electric push rod 22. A third electric push rod 24 is fixedly connected to the top of the side of the telescopic bracket 23 away from the second electric push rod 22. A receiving column 25 is rotatably connected to the outer side of the third electric push rod 24. A friction mechanism 26 is fixedly connected to the outer side of the receiving column 25. The second electric push rod 22 is raised and lowered to control the height of the component, which is convenient for adjustment according to the grinding surface of the material. The telescopic bracket 23 is extended and retracted to facilitate the friction mechanism 26 to fit against the material surface, thus making it suitable for materials of different sizes and avoiding affecting the grinding effect. The third electric push rod 24 controls the raising and lowering of the receiving column 25 to improve the flexibility of the component and increase the control details of the component. Then, by rotating the material and rubbing it against the friction mechanism 26, the polishing effect is achieved.

[0041] The friction mechanism 26 includes a receiving block 261. One side of the receiving block 261 is fixedly connected to the outer side of the receiving column 25. A fourth spring 262 is provided on the inner side of the receiving block 261. A cylindrical block 263 is fixedly connected to one side of the fourth spring 262. An annular flexible plate 264 is fixedly connected to the outer side of the cylindrical block 263 away from the fourth spring 262. A friction band 265 is sleeved in the groove on the side of the annular flexible plate 264 away from the cylindrical block 263. A square cutout 266 is provided on the outer side of the friction band 265. The friction band 265 rubs against the material surface to achieve the effect of grinding the material. The square cut 266 and grooves enhance the chip removal effect and reduce the adsorption of impurities. Secondly, the grooves enhance the heat dissipation effect, effectively reducing the heat generated by friction and preventing the material from overheating and deforming. When in contact with the rotating material surface, the cylindrical block 263 slides inward toward the receiving block 261 according to the external pressure. This facilitates the deformation of the component through contraction, making it easier to fit the material surface, thereby improving the grinding effect, reducing grinding dead angles, and expanding the applicability of the equipment.

[0042] In use, the operator places the material on top of the clamping mechanism 17. The buffer mechanism 18 reduces the pressure generated during material placement, while simultaneously increasing the wear resistance of the equipment and components, reducing wear between the equipment and the material, thereby extending the service life of the components and reducing impacts on the material surface. Secondly, the buffer mechanism 18 reduces the amplitude of vibration generated during material placement, thereby improving the stability of the equipment. Then, the clamping mechanism 17 clamps the material to maintain its stability, ensuring subsequent operations and preventing derailment. The clamping mechanism 17 contains a clamping mechanism 174, which increases the clamping capacity for materials of different sizes and shapes, thus expanding the applicability of the clamping mechanism. To improve the clamping and fixing effect and reduce the probability of material derailment, after the material is fixed, the steering mechanism 16 is rotated by the motor 3, so that the material rotates and rubs against the surface of the processing mechanism 2, thereby polishing the material. During the polishing process, sparks and debris are easily generated. To avoid affecting the workers and the environment, the annular plate 13 inside the composite mechanism 1 shields the material during the polishing process, thereby limiting the splashing of sparks and debris. On the one hand, it reduces the splashing of debris, prevents the inhalation of debris into the respiratory tract, reduces safety hazards, and facilitates subsequent cleaning. On the other hand, it reduces the amount of sparks, prevents sparks from flying, reduces safety hazards, and optimizes the working environment.
